The mass and environmental dependence on the secular processes of AGN in terms of morphology, colour, and specific star-formation rate

, 2018
Galaxy mass and environment play a major role in the evolution of galaxies. In the transition from star-forming to quenched galaxies, Active galactic nuclei (AGN) have also a principal action. However, the connections between these three actors are still

Hydrogen peroxide ‐ responsive aminoferrocene prodrugs

European Journal of Organic Chemistry, Accepted Article.
Aminoferrocene (AF)‐based prodrugs are activated in cancer cells through reactions with H₂O₂ and other reactive oxygen species (ROS), generating electron‐rich AF’s. These, in turn, induce the production of highly toxic O2·‐ and HO·, leading to cancer cell death.

The Infrared Traced Star Formation Rates of Associated Absorption Lines Quasars

The Astrophysical Journal
Some optically selected quasars exhibit Mg ii- associated absorption lines (AALs), and their origin remains unclear. In this paper, we compile a sample of 1769 quasars, with or without Mg ii AALs, of which 1689 are far-infrared (FIR) detected quasars and

ISO observations of four active galaxies

, 2003
We present ISO PHOT-S spectra of four galaxies known or suspected to host a central AGN, selected from the initial Iras/Rosat sample of Boller et al. (1992).

Kiloparsec-scale Neutral Iron Kα Emission in the Starburst-AGN NGC 4945: A Relic AGN Outflow?

The Astrophysical Journal
NGC 4945 contains a well-known heavily obscured active galactic nucleus (AGN) at its core, with prior reports of strong nuclear and off-nuclear neutral Fe K α emission due to the AGN activity. We report the discovery of very extended Fe K α emission with

Tumor desialylation surpasses anti‐PD‐L1 checkpoint therapy in restoring anti‐tumor immunity in a murine model for colorectal cancer

International Journal of Cancer, EarlyView.
What's New? Our research highlights how tumor sialylation affects tumor growth and reshapes the immune tumor microenvironment in colorectal cancer. We demonstrate for the first time that complete removal of sialic acids from colorectal tumor cells elicits a robust anti‐tumor immune response, but does not enhance anti‐PD‐L1 blockade efficacy.

Properties of Voids and Void Galaxies in the TNG300 Simulation

The Astrophysical Journal
We investigate the properties of voids and void galaxies in the TNG300 simulation. Using a luminous galaxy catalog and a spherical void-finding algorithm, we identify 5078 voids at redshift z = 0.

Gut microbiota and tuberculosis

iMeta, EarlyView.
This review explores the intricate relationship between gut microbiota (GM) and tuberculosis (TB). The figure illustrates the bidirectional effects between GM dynamics and TB progression, as well as the interactions between the GM and antituberculosis drugs.

The environment of active objects in the nearby universe

, 2002
We study the galaxy environment of active galaxies, radio-loud and radio-quiet quasars in the redshift range $0.1\leq z\leq0.25$. We use APM galaxies in order to explore the local galaxy overdensity and the $b_J-R$ colour distribution of neighbouring ...
